Application July 22, 1952, Serial No. 300,140 l I (cl. 5-109) 3 Claims.v

This invention relates to baby cribs, and more particularly to a baby crib provided with means for oscillating same.

A main object of the invention is to provide a novel and improved electrically driven oscillating baby crib, said baby crib being simple in construction, involving relatively few parts, and being easy to install.

A further object of the invention is to provide an improved electrically driven oscillating baby crib which involves inexpensive components, which is sturdy in construction, which provides a smooth oscillating action, and which is safe to use.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 1 is a side elevational view of an improved baby crib constructed in accordance with the present invention.

Figure 2 is an end elevational view, partly broken away, of the baby crib of Figure 1.

Figure 3 is an enlarged cross sectional detail View taken on line 3--3 of Figure l.

Figure 4 is an enlarged cross sectional detail view taken on the line 4-4 of Figure 1.

Figure 5 is an enlarged fragmentary cross sectional detail View taken on the line 5 5 of Figure 2.

Figure 6 is an enlarged cross sectional detail view taken on line 6 6 of Figure 5.

Figure 7 is an enlarged cross sectional detail view taken on the line I-l of Figure 3.

Figure 8 is an enlarged cross sectional view taken on the line 8-8 of Figure 4.

Referring to the drawings, the baby crib is designated generally at Il and comprises the transverse end boards I2 and I3, which may be the end boards of a conventional baby crib of the stationary type. The end boards i2 and I3 are connected by the longitudinal rod members I4 to dei-lne a rigid rectangular framework, and the end boards may comprise vertical corner posts elements I5, I5 connected at their top and bottom portions by the transverse rod members I6 and at their intermediate portions by the spaced horizontal tranverse bars I'I, I1 which are grooved to receive the end panels I8.

Designated at I 9 is the baby bed which inf cludes the transverse end walls 20 and 2i. Secured to the upper portion of the transverse end wall 20 is a bracket member 22 formed with the longitudinally extending shaft element 23 which extends rotatably through a bearing 24 provided in the upper portion of the panel element of the end board I2, as shown in Figure 5, and secured to the upper portion of the end wall 2l of the baby bed is another bracket plate 25 formed integrally with the longitudinally extending shaft element 26, longitudinally aligned with the shaft element 23, which extends rotatably through a bearing 21 secured in the upper portion of the panel I8 of end board I3. The baby bed I9 is thus supported for oscillation around a longitudinal axis located at its upper portion.

vertically secured to and extending through the bars Il, I1 are the spaced rod members 28, 28. Adjustably secured to the rod members 28, 28 as by clamping bars 29 and 30 transversely embracing said rod members is a vertical plate member 3 I, said plate member being secured to the clamping bars 25 and 30 by respective bolts 32 and wing nuts 33, as shown in Figure 3. The clamping bars 29 and 30 are provided at their ends with the clamping bolts 34 provided with Wing nuts 35, whereby the plate member 3| may be adjustably secured at a desired elevation along the rods 28, 28. The plate member 3l is formed f with a horizontal stud element 36, and pivotally secured thereto for rotation around a longitudinal horizontal axis is an electric motor 3'! mounted substantially vertically, as shown in Figures 1 and 3 and having the depending shaft 38. Secured on the shaft 38 is a relatively small gear 39 which meshes with a larger gear 40 journalled to the bottom of the motor housing and formed in its face portion with an eccentrically located, generally circular groove 4I. Formed integrally with the stud element 36 is the depending arm 42 which is provided at its ends with the vertical roller 43 engaging in the groove 4|. Since the arm 42 is stationary, rotation of the motor shaft 38 causes the motor to oscillate around its horizontal pivotal supporting axis, the axis of the gear 40 being located in transverse alignment with the motor shaft 38, whereby the rotation of the motor shaft produces an oscillating reaction causing the motor to swing from side to side. The lower end of the motor shaft 38 extends through an aperture in a longitudinally extending plate member 44 secured to the bottom of the baby bed IS, whereby the os cillation of the motor 3l is transmitted tothe baby bed.

It will be readily apparent that when the motor 31 is energized, the baby bed I9 will be caused to oscillate around its axis of rotation.

As shown in Figure 7, the motor 3l is rotatably supported in the stud 36, the motor being pro- 3 vided with a supporting shaft 45 which is rotatably received in stud 36, said shaft 45 being formed with an annular groove 46 in which is engaged the end of a retaining screw 41 for normally preventing disengagement of the shaft 45 from the supporting stud 36.

While a specific embodiment of an improved oscillating baby crib has been disclosed in the foregoing description, it will be'understood thatf various rnodincations Within thel spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations bev placed on the invention except as dened by the scope of the appended claims.

What is claimed is:
